Wideband Marine DF Antenna
DF-A0123
The DF-A0123 is a wideband DF antenna suitable for fixed mast-mounted and marine applications. A hybrid between the compact DF-A0037 and the full-size DF-A0001, the antenna has a full-size lowband array for best DF performance at low frequencies where the compact array is small. Inside the radome are two pentagonal arrays for the middle and high frequency ranges. Secondary arrays of dipoles and monopoles are combined, to provide omni outputs up to 3.6 GHz.A cavity inside the antenna, approximately 350 mm wide by 370 mm high, allows an RF switch to be integrated into the antenna, reducing cable loss and weight. The cavity slides open, the switch can be installed by one person, on a mast, without a crane
